Jane Street führt die 105 Millionen Dollar schwere Serie A von Antithesis an, um deterministische Simulationstests zum neuen Standard zu machen

Eine einzigartige Investition des Quantenhandelsriesen signalisiert einen Wandel in der Art und Weise, wie komplexe Systeme getestet werden.

TYSONS CORNER, Virginia, 4. Dezember 2025 — Antithesis gab heute eine Serie-A-Runde in Höhe von 105 Millionen US-Dollar unter der Leitung von Jane Street bekannt, dem globalen technologiegetriebenen quantitativen Handelsunternehmen, das für den Aufbau einiger der weltweit fortschrittlichsten Softwaresysteme bekannt ist. Die Investition unterstreicht die Bedeutung von Antithesis als kritische Infrastruktur für Unternehmen, die komplexe, verteilte Systeme betreiben. Jane Street ist sowohl Investor als auch Kunde von Antithesis.

Zu den weiteren Investoren gehören Amplify Venture Partners, Spark Capital, Tamarack Global, First In Ventures, Teamworthy Ventures, Hyperion Capital sowie Privatpersonen wie Patrick Collison, Dwarkesh Patel und Sholto Douglas sowie weitere neue und wiederkehrende Investoren. Das Kapital wird verwendet, um die Produktinnovation von Antithesis zu beschleunigen und die Marktpräsenz in Nordamerika, Europa sowie Asien zu erhöhen.

Softwaresysteme sind komplexer geworden, und da KI das Volumen des produzierten Codes beschleunigt, können herkömmliche Tests nicht mehr Schritt halten. Heutzutage verlassen sich die meisten Unternehmen immer noch auf beispielbasierte Tests (ob von Ingenieuren oder von KI geschrieben). Diese Methoden erfassen zwar oberflächliche Probleme, können jedoch nicht zuverlässig die tiefgreifenden, sich entwickelnden Verhaltensweisen aufdecken, die zu Ausfällen, Datenbeschädigungen und kaskadenartigen Systemausfällen führen.

Antithesis ersetzt dies durch deterministische Simulationstests: Es wird eine vollautomatisierte, massiv parallele Simulation des zu validierenden Systems ausgeführt, die monatelanges Verhalten in der produktiven Umgebung auf wenige Stunden verdichtet. Die Plattform untersucht Randfälle, injiziert häufige Fehler, validiert die Korrektheit und reproduziert jeden Fehler perfekt, sodass Ingenieure Probleme mit beispielloser Geschwindigkeit sowie Zuverlässigkeit beheben können.

„Software ist heute die Grundlage von allem, und je komplexer und verteilter Systeme werden, desto mehr braucht die Welt ein neues Testmodell, das Korrektheit garantiert”, sagte Will Wilson, Geschäftsführer von Antithesis. „Mit dieser Finanzierung bauen wir die Infrastruktur aus, die Zuverlässigkeit nicht nur erreichbar, sondern zur Selbstverständlichkeit macht, so wie wir auch erwarten, dass Ampeln jedes Mal funktionieren. Unsere Kundschaft beweist bereits, dass deterministisch validierte Systeme schneller ausgeliefert werden, ohne zu versagen, und ein tieferes Vertrauen schaffen.”

„Jane Street betreibt einige der anspruchsvollsten verteilten Systeme der Welt, und Antithesis hat uns geholfen, Probleme aufzudecken, die keine andere Testmethode finden konnte”, sagte Doug Patti, Ingenieur bei Jane Street. „Wir legen die Messlatte für Technologien, auf die wir uns verlassen, sehr hoch und für Unternehmen, in die wir investieren, sogar noch höher. Es ist zwar selten, dass wir eine frühe Runde leiten, aber Antithesis ist uns um Jahre voraus, und wir glauben, dass deterministische Simulationstests in allen Branchen grundlegend sein werden.”

Auswirkungen auf Kunden in den Bereichen Finanzen, KI, Blockchain und Dateninfrastruktur
Antithesis wird bereits von Unternehmen eingesetzt, deren Systeme nicht ausfallen dürfen:

  • Jane Street verlässt sich auf Antithesis, um komplexe verteilte Systeme zu validieren, die für den Betrieb ihres globalen Handelsgeschäfts entscheidend sind.
  • Ethereum nutzte Antithesis, um sein globales Netzwerk unter extremen Bedingungen vor The Merge zu simulieren und kritische Probleme aufzudecken, die den historischen Übergang auf Proof of Stake hätten gefährden können.
  • MongoDB nutzt Antithesis, um Kernkomponenten seiner Datenbankplattform rigoros zu testen und hilft den Ingenieuren, subtile Probleme zu erkennen, bevor sie die Kunden erreichen.

Diese Beispiele spiegeln einen schnell wachsenden Kundenstamm in den Bereichen Finanzwesen, Infrastrukturplattformen und Organisationen wider, die fortschrittliche KI-Systeme entwickeln. Antithesis hat seinen Umsatz in den vergangenen zwei Jahren um mehr als das Zwölffache gesteigert und wächst weiterhin rasant.

Verwendung der Mittel
Mit der neuen Finanzierung wird Antithesis:

  • Engineering-Teams erweitern, um ihre deterministische Simulations-Engine weiter zu stärken
  • Die Analysefähigkeit und Autonomie der Plattform weiter ausbauen
  • Eine erstklassige Vertriebs- und Marketingorganisation aufbauen
  • Markteinführungsaktivitäten in Nordamerika, Europa und Asien skalieren
  • Die Verfügbarkeit über Cloudkanäle, einschließlich des AWS Marketplace, weiter ausbauen

Informationen zu Antithesis
Antithesis ist ein grundlegend neuer Weg, um zu überprüfen, ob Software korrekt funktioniert, bevor sie veröffentlicht wird. Es führt eine vollständig deterministische, massiv-parallele Simulation durch, die in wenigen Stunden eine jahrelange Produktion unter realen Bedingungen testet. Antithesis erforscht auf intelligente Weise die entlegensten Winkel Ihrer Codebasis und fügt strategisch häufige Fehler ein, um sicherzustellen, dass sich das System immer wie vorgesehen verhält. Die Plattform reproduziert jeden gefundenen Fehler exakt in ihrer einzigartigen Umgebung zur schnellen Fehlerbehebung. Das Unternehmen hat seinen Sitz in Nord-Virginia, wurde 2018 gegründet und ist 2024 aus dem Stealth-Modus hervorgegangen. Weitere Informationen finden Sie auf https://antithesis.com/.

Jane Street lidera la ronda Serie A de 105 millones de dólares de Antithesis

-Jane Street lidera la ronda Serie A de 105 millones de dólares de Antithesis para convertir las pruebas de simulación determinista en el nuevo estándar

Una inversión única del gigante del trading cuantitativo marca un cambio en la forma en que se evaluarán los sistemas complejos.

TYSONS CORNER, Va., 3 de diciembre de 2025 — Antithesis anunció hoy una ronda de financiación Serie A de 105 millones de dólares liderada por Jane Street, la firma global de trading cuantitativo basada en tecnología, conocida por desarrollar algunos de los sistemas de software más avanzados del mundo. La inversión subraya el surgimiento de Antithesis como infraestructura crítica para empresas que operan sistemas complejos y distribuidos. Jane Street es inversora y cliente de Antithesis.

Entre los inversores adicionales se incluyen Amplify Venture Partners, Spark Capital, Tamarack Global, First In Ventures, Teamworthy Ventures, Hyperion Capital y personas como Patrick Collison, Dwarkesh Patel y Sholto Douglas, junto con otros inversores nuevos y recurrentes. El capital se utilizará para acelerar la innovación de productos de Antithesis y escalar sus operaciones de comercialización en Norteamérica, Europa y Asia.

Los sistemas de software se han vuelto más complejos y, a medida que la IA acelera el volumen de código producido, las pruebas tradicionales no pueden seguir el ritmo. Hoy en día, la mayoría de las organizaciones aún dependen de pruebas basadas en ejemplos (ya sea desarrolladas por ingenieros o por IA). Estos métodos detectan problemas superficiales, pero no pueden exponer de forma fiable los comportamientos profundos y emergentes que causan interrupciones, corrupción de datos y fallos en cascada del sistema.

Antithesis sustituye esto por pruebas de simulación deterministas: ejecuta una simulación totalmente automatizada y masivamente paralela del sistema que se está validando, que comprime meses de comportamiento de producción en horas. La plataforma explora casos extremos, inyecta fallos comunes, valida la corrección y reproduce perfectamente cualquier fallo para que los ingenieros puedan solucionar problemas con una velocidad y una confianza sin precedentes.

“El software ahora lo sustenta todo, y a medida que los sistemas se vuelven más complejos y distribuidos, el mundo necesita un nuevo modelo de pruebas que garantice la precisión”, afirmó Will Wilson, consejero delegado de Antithesis. “Con esta financiación, ampliamos la infraestructura que hace que la fiabilidad no solo sea alcanzable, sino esperable, tal como esperamos que los semáforos funcionen siempre. Nuestros clientes ya están demostrando que los sistemas validados determinísticamente se entregan más rápido, sin fallos, y generan una mayor confianza”.

“Jane Street gestiona algunos de los sistemas distribuidos más exigentes del mundo, y Antithesis nos ha ayudado a descubrir problemas que ningún otro método de pruebas podría detectar”, afirmó Doug Patti, ingeniero de Jane Street. “Tenemos estándares muy altos para la tecnología en la que confiamos, y estándares aún más altos para las empresas en las que invertimos. Si bien liderar una ronda temprana es poco común para nosotros, Antithesis lleva años de ventaja, y creemos que las pruebas de simulación deterministas se convertirán en fundamentales en todos los sectores”.

Impacto en el cliente en finanzas, IA, blockchain e infraestructura de datos
Antithesis ya es utilizado por organizaciones cuyos sistemas no pueden fallar:

  • Jane Street depende de Antithesis para validar sistemas distribuidos complejos, esenciales para el funcionamiento de su negocio de comercio global.
  • Ethereum utilizó Antithesis para simular su red global en condiciones extremas antes de la Fusión, lo que reveló problemas críticos que podrían haber puesto en peligro la histórica transición a la Prueba de Participación.
  • MongoDB utiliza Antithesis para probar rigurosamente los componentes principales de su plataforma de bases de datos, lo que ayuda a los ingenieros a detectar problemas sutiles antes de que afecten a los clientes.

Estos ejemplos reflejan una base de clientes en rápida expansión en el sector financiero, plataformas de infraestructura y organizaciones que desarrollan sistemas avanzados de IA. Antithesis ha multiplicado sus ingresos por más de 12 en los últimos dos años y continúa creciendo rápidamente.

Uso de los fondos
Con la nueva financiación, Antithesis:

  • Ampliará los equipos de ingeniería para fortalecer su motor de simulación determinista
  • Mejorará la inteligencia y la autonomía de la plataforma
  • Desarrollará una organización de ventas y marketing de primer nivel
  • Escalará las operaciones de GTM en Norteamérica, Europa y Asia
  • Aumentará la disponibilidad a través de canales en la nube, incluido AWS Marketplace

Acerca de Antithesis
Antithesis es una forma completamente nueva de validar el correcto funcionamiento del software antes de su lanzamiento.

Jane Street dirige la série A de 105 millions de dollars d’Antithesis en faisant des tests de simulation déterministes pour tester la nouvelle norme

Un investissement unique du géant de la négociation quantique marque un changement dans la manière dont les systèmes complexes seront testés.

TYSONS CORNER, Va., 3 décembre 2025 — Antithesis a annoncé aujourd’hui une levée de fonds de 105 millions de dollars de série A, menée par Jane Street, la société mondiale de trading quantitatif orientée technologie, connue pour avoir construit certains des systèmes logiciels les plus avancés au monde. L’investissement souligne l’émergence d’Antithesis en tant qu’infrastructure critique pour les entreprises exploitant des systèmes complexes et distribués. Jane Street est à la fois un investisseur et un client d’Antithesis.

Parmi les autres investisseurs figurent Amplify Venture Partners, Spark Capital, Tamarack Global, First In Ventures, Teamworthy Ventures, Hyperion Capital, ainsi que des particuliers tels que Patrick Collison, Dwarkesh Patel et Sholto Douglas, aux côtés d’autres investisseurs, nouveaux et anciens. Le capital sera utilisé pour accélérer l’innovation des produits d’Antithesis et développer ses opérations de commercialisation en Amérique du Nord, en Europe et en Asie.

Les systèmes logiciels sont devenus plus complexes et, à mesure que l’IA accélère le volume de code produit, les tests traditionnels n’arrivent plus à suivre le rythme. Aujourd’hui, la plupart des entreprises dépendent encore de tests basés sur des exemples (qu’ils soient rédigés par des ingénieurs ou par l’IA). Ces méthodes permettent de détecter les problèmes de surface, mais ne peuvent pas mettre en évidence de manière fiable les comportements profonds et émergents à l’origine des pannes, de la corruption des données et des défaillances en cascade des systèmes.

Antithesis s’y substitue grâce à des tests de simulation déterministes : l’exécution d’une simulation entièrement automatisée et massivement parallèle du système en cours de validation, qui comprime des mois de comportement de production en quelques heures. La plateforme explore les cas limites, injecte des défauts courants, valide l’exactitude et reproduit parfaitement toute défaillance afin que les ingénieurs puissent résoudre les problèmes avec une rapidité et une confiance sans précédent.

“Aujourd’hui, tout repose sur les logiciels, et comme les systèmes deviennent de plus en plus complexes et distribués, le monde a besoin d’un nouveau modèle de test qui garantisse l’exactitude”, a déclaré Will Wilson, CEO d’Antithesis. “Grâce à ce financement, nous développons l’infrastructure qui rend la fiabilité non seulement réalisable, mais attendue, tout comme nous attendons des feux de circulation qu’ils fonctionnent à chaque fois. Nos clients prouvent déjà que les systèmes validés de manière déterministe sont livrés plus rapidement, sans rupture, et qu’ils génèrent davantage de confiance”.

“Jane Street gère certains des systèmes distribués les plus exigeants au monde, et Antithesis nous a aidés à découvrir des problèmes qu’aucune autre méthode de test n’aurait pu déceler”, a déclaré Doug Patti, ingénieur chez Jane Street. “Nous plaçons la barre très haut en ce qui concerne la technologie dont nous dépendons, et encore plus haut en ce qui concerne les entreprises dans lesquelles nous choisissons d’investir. Bien qu’il soit rare que nous menions un premier tour de table, Antithesis a des années d’avance, et nous pensons que les tests de simulation déterministes deviendront essentiels dans tous les secteurs.

Impact sur le client dans les secteurs de la finance, de l’IA, de la blockchain et de l’infrastructure des données
Antithesis est déjà utilisé par des entreprises dont les systèmes ne peuvent pas tomber en panne :

  • Jane Street fait appel à Antithesis pour valider des systèmes distribués complexes essentiels au fonctionnement de ses activités commerciales mondiales.
  • Ethereum a utilisé Antithesis pour simuler son réseau mondial dans des conditions extrêmes avant la mise à jour The Merge, révélant ainsi des problèmes critiques qui auraient pu compromettre la transition historique de la preuve d’enjeu.
  • MongoDB utilise Antithesis pour tester rigoureusement les principaux composants de sa plateforme de base de données, ce qui aide les ingénieurs à détecter les problèmes subtils avant qu’ils ne touchent les clients.

Ces exemples indiquent une base de clients en pleine expansion dans le domaine de la finance, des plateformes d’infrastructure et des entreprises construisant des systèmes d’IA avancés. Antithesis a multiplié son chiffre d’affaires par plus de 12 au cours des deux dernières années et continue à se développer rapidement.

Utilisation du produit
Avec le nouveau financement, Antithesis va :

  • Développer les équipes d’ingénieurs pour renforcer son moteur de simulation déterministe
  • Faire progresser l’intelligence et l’autonomie des plateformes
  • Mettre en place une organisation de vente et de marketing de classe mondiale
  • Développer les opérations GTM en Amérique du Nord, en Europe et en Asie
  • Accroître la disponibilité par le biais de canaux dans le cloud, notamment AWS Marketplace

À propos d’Antithesis
Antithesis est une toute nouvelle méthode permettant de valider le bon fonctionnement d’un logiciel avant sa mise sur le marché. Elle effectue une simulation entièrement déterministe et massivement parallèle qui permet de tester en quelques heures des années de production dans le monde réel. Antithesis explore intelligemment les coins les plus reculés de votre base de code, en injectant stratégiquement des fautes courantes pour s’assurer que le système se comporte toujours comme prévu. La plateforme reproduit parfaitement les bogues qu’elle détecte dans son environnement unique pour effectuer un débogage rapide.

Gradial Raises $35 Million to Redefine Enterprise Marketing Through AI Agents

SEATTLE, Dec. 3, 2025 — Gradial, the enterprise software company defining agentic marketing operations, today announced it has raised $35 million in Series B funding led by VMG Partners, with participation from existing investors Madrona and Pruven Capital. This brings the company’s total funding since launching to $55 million.

While early AI tools focused on generating content, Gradial built its foundation on managing the content supply chain, the operational backbone of enterprise marketing. Gradial’s agents automate the execution layer of marketing: authoring, brand redesigns, QA, and large-scale campaign operations across existing systems and workflows.

“Every enterprise marketing team faces the same challenge,” said Doug Tallmadge, Co-Founder and CEO of Gradial. “Their current tools and processes are too fragmented for them to move at the speed they need. Gradial agents live inside the workflow and learn to do the work just like a human employee would. This isn’t just another gen AI experiment – it’s a platform that transforms the enterprise through real and tangible ROI.”

Gradial’s customers include many global enterprises, making Gradial one of the only agentic startups deployed at scale in the Fortune 1000. These teams came to Gradial with the same challenge: operations, not creative, are the bottleneck for launching personalized campaigns. Ten or more roles touch every marketing request—project managers, designers, developers, content authors, copywriters, and QA specialists—slowing execution and blocking personalization at scale. Consumers demand fresh, personalized content, but weeks of work and review cycles sit between a marketing brief and a customer facing experience.

Gradial’s agents streamline marketing operations for leading brands like T-Mobile by integrating directly into enterprise tools and systems and reasoning through complex work. Day to day, Gradial agents read context from fragmented systems and give marketers a team of digital coworkers to execute campaign operations, eliminating backlogs and speeding migrations. Gradial also ensures that every request is 100% compliant, brand adherent, and accessible so review cycles are short and systematic.

“Gradial is achieving our goal of reducing time to market by 80% plus which is opening up valuable capacity to take on 10x more volume of work, especially as it relates to contextual experiences,” said Nick Pappas, Senior Director Digital Business Management at T-Mobile. “Additionally, the time saving is also allowing for increased focus on more complex strategic efforts, because every day, content management is automated and accelerated.”

By solving for workflow complexity, Gradial enables marketing teams to reduce execution time and increase campaign throughput while maintaining quality, brand, and compliance adherence.

“Our ecosystem of enterprise marketers tells us over and over that the operational drag of deploying content is the biggest barrier to delivering quality marketing at scale,” said Sam Shapiro, Partner at VMG Partners. “The biggest and most innovative brands in the world spend tens of millions of dollars on content delivery drudgery, and Gradial revolutionizes that. Their excitement about Gradial’s ability to free them from execution and refocus on strategic impact has been exceptional.”

The company will use the new funding to accelerate development of its platform and expand its Seattle-based team across engineering, product, and go-to-market.

About Gradial
Gradial is a leading agentic AI company transforming enterprise marketing operations.
